Apple mail client is rejecting my password, but it works via the internet

I get the same kind of message: "The MobileMe IMAP server “imap.mail.me.com” rejected the password". I've cleaned my permissions, restarted, changed my password online ...all to no avail. Icloud is offlinein Mail on my MacBook Pro despite having reset my password several times in preferences. Oddly I can pick up and send emails via the cloud on my ipod touch using my new password.

I'm having the same problem. It just started today. I've tried using my Mac booted to a back up drive and also tried an old iPhone and they are all the same, no good. It works on my iPad, but it accesses iCloud without using IMAP. The problem must be with the iCloud Mail IMAP server. Hopefully, it will be fixed soon. I recommend that you don't change any of your settings for awhile. You might get your system messed up and cause yourself more problems.

Ronald is right. Don't change settings. Something is wrong with the IMAP server.

This happens from time to time. The iCloud status page is only really useful for historical information. In my experience, it never shows a problem until the problem has passed.

Same here.

IMAP works on the default mail app on my OS X 10.9 macbook pro.

icloud.com interface also works.

iPad and iPhone will not work since this afternoon. They usually work fine. I get a message saying i'm using the wrong username/password, which is not true because i'm able to login with the web icloud.com interface. I have tried changing my password: still works on my mac and icloud.com but didn't solve my problem with my iPad and iPhone.

As CAPTJON mentionned, I have tried it on my android tablet and I get an incorrect username/password error. It used to work fine on this android tablet also.

Windows mail client won't work.

My friend let me try his icloud account on my android tablet and it worked...It also worked on my ipad... So this is giving me a hint that maybe the problem isn't related to all of the @me and @icloud emails?
